Don't do all the reinstalls. It is in firmware or the gcode you send or a combination.
My problem is that I'm too busy to test myself at the moment.
You could test without M3 and only use increasing E values where you want to laser. That is the second mode to operate. Or you add some print comments in Commands.cpp where G0/G1 is parsed. You will see it contains the test for laser on/off which in some cases fail, so a variable it depends on seems to be initialized wrong or get overwritten unexpectedly.
I am not a programmer so this is abracadabra for me.
For now I can use software I found which uses M3 and M5 and is working.
I's rather use the right way; repetier plugin for inkscape.
Since your're too busy I just wait this issue to be solved in the future.
One last question for now.
Where is the list of printed models located that show up when starting repetier?
Thnks
